In tunnel mode, IPsec encrypts both the IP payload and the header to protect an entire IP packet by encapsulating it with an AH or ESP header and an additional IP header. This mode is useful for protecting traffic between different networks and is primarily used for interoperability with gateways. The tunnel mode of IPsec is generally implemented in configurations such as gateway-to-gateway, server-to-gateway and server-to-server. The IPsec tunnel mode is useful in protecting traffic while it is passing through untrusted networks.
